One of the basic things about a string is that it can vibrate in many different shapes or forms, which gives music its beauty.

You have that one basic string, but it can vibrate in many ways. But we're trying to get a lot of particles because experimental physicists have discovered a lot of particles.

String Theory describes energy and matter as being composed of tiny, wiggling strands of energy that look like strings. And the pitch of a string's vibration determines the nature of its effect.

In essence, String Theory describes space and time, matter and energy, gravity and light, indeed all of God's creation... as music.

The central idea of string theory is quite straightforward. If you examine any piece of matter ever more finely, at first you'll find molecules, atoms, sub-atomic particles. Probe the smaller particles, you'll find something else, a tiny vibrating filament of energy, a little tiny vibrating string.

What the string theorists do is arguably physics. It deals with the physical world. They're attempting to make a consistent theory that explains the interactions we see among particles and gravity as well. That's certainly physics, but it's a kind of physics that is not yet testable.

The bottom string is tuned to an open G.

Every string theory that's been written down says the speed of light is universal. But other ideas about quantum gravity predict the speed of light has actually increased.

I'm a firm believer that lighting affects mood, and twinkly lights on strings bring something magical to occasions ranging from concerts to weddings, though I'm fond of using them as year-round home decor. There's a reason why they're sometimes called fairy lights. When the night is right, there aren't any strings at all.

String theory is an attempt at a deeper description of nature by thinking of an elementary particle not as a little point but as a little loop of vibrating string.
